106 mined out side end 114）.In shown construction, mined out side end 114 is generally horizontally with transporter pan portion 79 into always
Line.
The further detail below of working face siding track 46 will be discussed with reference to figure 3.In this manual, upper and lower, left and right, vertical
With level as shown in FIG. 3.Loading part 90 is connected to body 86, and with top surface 118 and loads surface 122.Dress
Carry surface 122 to be disposed between two connection parts 102, and extend between two connection parts 102.In shown construction, material
Expect lower section extension of the cavity 106 in the entirely lower section on loading surface 122 and the part in top surface 118.In addition, in shown structure
In making, relative to the work surface side end 98 of transporter groove 70,74, loading part 90 is substantially most of long on work surface side
Degree is all angled.
The mined out side 126 in top is defined as approaching with the mined out side end of top surface 118.Top work surface side 130
It is limited at the transition part office from horizontal top surface 118 to angled loading surface 122.Load the quilt of working face side 134
It is defined to the work surface side end with loading surface 122（The work surface side end on the top of working face siding track 46）It is close.
The overall width 138 of the upper surface of loading part 90 is defined（In general horizontal face）Loading working face side 134
Between the mined out side 126 in top.Top surface width 142 is limited at the mined out side 126 in top and top work surface side 130
Between, load face width 146 and be defined（In general horizontal face）Loading working face side 134 and top work surface side
Between 130.
Load face width 146 is at least overall width 138 about 25%, more specifically about the 40% of overall width 138.
In illustrated embodiment, face width 146 is loaded as about the 50% of overall width 138（For example, about 48%）.In other words, top surface is wide
Degree 142 is only about the 75% of overall width 138, more specifically only about the 60% of overall width 138.In the embodiment shown, push up
Face width 142 is about the 50% of overall width 138（For example, about 52%）.
Angle 150 is loaded to be limited between at least a portion on loading surface 122 and at least a portion of top surface 118.
In shown construction, top surface 118 and load the substantially rectilinear shape in surface 122, load angle 150 be limited at surface 118,
Between 122 line part.
Between loading angle 150 is about 25 degree to 55 degree, between more specifically about 30 degree to about 50 degree.Shown loading angle
150 be about 45 degree.In shown construction, load surface 122 be arranged such that load surface 122 limit face not with toe anchor
Gu device flange 82 is intersecting.
Flange height 154 is limited in the face horizontal substantially with ledge surface 94.Material cavity height 158 is limited at
The top surface of material cavity 106（Or the basal surface of loading part 90）On vertical direction between ledge surface 94.Load high
Degree 162 is limited at the minimum point for loading surface 122（For example, loading at working face side 134）Between ledge surface 94
Vertical direction on.Top surface height 166 is limited on the vertical direction between top surface 118 and ledge surface 94.
Material cavity height 158 is less than the pact of about the 80% of top surface height 166, more particularly less than top surface height 166
70%.Shown material cavity height 158 is about the 60% of top surface height 166（For example, about 61%）.
Loading height 162 is less than about the 75% of about the 85% of top surface height 166, more particularly less than top surface height 166.
Shown loading height 162 is about the 70% of top surface height 166（For example, about 71%）.
During cutting operation（Referring to Fig. 1 and Fig. 4）, flitting 22 rotates cutting-cylinder 26, with from mining face
30 cutting material M.With material M cutting, cutting-cylinder 26 also promotes material M towards AFC14.Loading part 90 is in work surface side
The loading hole 170 fully increased is provided between track 46 and flitting 22.In this way, even in low coal seam height equipment（Example
Such as, 3 meters or lower）In, material M is also easy to be loaded into transporter disk 54.Fig. 1 and Fig. 4 shows material M by from mining face 30
Cut off and be loaded into by flitting 22 on AFC14.
During forward operation（Referring to Fig. 5 to Fig. 6）, AFC14 is advanced to remaining material heap using hydraulic ram 174
In M.Hydraulic ram 174 promotes AFC towards mining face 30, so as to promote material M to cross working face siding track 46 and positioned at transport
On machine disk 54.Material cavity 106 and the angled surface 122 that loads together cooperate with toe anchor flange 82, to provide dynamic
Load slope.Material M assembles in material cavity 106, and is deposited in downwards on toe anchor flange 82, flat so as to be formed
Sliding material M slopes, the angle on the material M slopes are substantially identical with the angle 178 at the angle 150 on loading surface 122.Angled dress
Carrying surface 122 and/or material cavity 106 allows material M steadily and being effectively loaded on transporter disk 54.
As material M flows on working face siding track 46, downward active force is applied on working face siding track 46.
During forward operation, the angled downward force for loading surface 122, material slope M and synthesis provides relatively stable AFC14.Change
Sentence is talked about, and as AFC14 is advanced in material heap M, AFC is less likely to rise, or material heap M is vertically upright drifted about.
On the contrary, AFC14 keeps being steadily contacted with ground, and smoothly it is moved in material heap M.In addition, utilize angled loading
Surface 122, AFC14 compacting material heap M during advance amount are less than the AFC of prior art.Fig. 5 to Fig. 6 shows that material M exists
Mobility status during forward operation on working face siding track 46.
Fig. 8 is shown with for the multiple into corner of double dozer intermediate channels（" double bull-dozers " profile）Working face
Siding track 446.Generally, double bull-dozer working face siding tracks 446 include toe anchor flange 482, body 486, loading part
490 and two connection parts 502.Toe anchor flange 482 defines the ledge surface 494 for supporting shoes department 34 in sliding manner.
Body 486 defines the transporter groove 470,474 extended to towards working face 30 in body 486.Body 486 is also set
It is equipped with transporter pan portion 478.Connection part 502 is positioned to receive locking device, by neighbouring double bull-dozer working face siding tracks
Road 446 links together, so as to form continuous AFC.
Loading part 490 defines working face side surface 506, main loading surface 510, secondary loading surface 514 and three connections
Surface 518.Loading part 490 plays a part of to provide the slope for material M, to be flowed on double bull-dozer working face siding tracks 446
Move on transporter.
Fig. 7 and Fig. 9 has been respectively compared the loading part 90 of current intermediate channel section 18 and pair of the intermediate channel section 218 of prior art
Answer portion 290.Figure 10 is the stereogram for making to compare the intermediate channel section 218 of clearly prior art.In fig.9, same components
200 are added with same identification number.
With reference to figure 7, Fig. 9 and Figure 10, the middle part of the overall width 138 of the loading part 90 of this intermediate channel 18 substantially with prior art
The total length 338 on the top 290 of groove section 218 is identical.However, the loading part 90 of intermediate channel 18 is in working face siding track 46 and roller
Relatively large gap or loading hole 170 are provided between coal-winning machine 22, so that a greater amount of material M can pass through gap or loading
Hole 170.Compared with the intermediate channel section 218 of prior art, intermediate channel section 18 provides greatly about 5 percent（5%）Loading hole
170.On the contrary, in the intermediate channel section 218 of prior art, top 290 takes the quite big of loading hole 178 in intermediate channel section 18
Open space.
Using this intermediate channel section 18, the height at the working face side of loading part 90（Load the dress at working face side 134
Carry height 162）Than the height of the corresponding position on the top 290 of the intermediate channel section 218 of prior art（About top surface height
366）It is relatively low.Using the loading height 162 of reduction, the height for carrying out compacting material M against working face siding track 45 is reduced.
The one or more independent characteristics or advantage of the present invention are proposed in claim that can be more than.
